TPS6123x 8-A Valley Current Synchronous Boost Converters with Constant Current  
Output Feature  
1 Features  
3 Description  
The TPS6123x is a high current, high efficiency  
synchronous boost converter with constant output  
current feature for single cell Li-Ion and Li-polymer  
battery powered products, in a wide range of power  
bank, tablet, and other portable devices. The IC  
integrates 14-mΩ/14-mΩ power switches and is  
capable of delivering up to a 3.5-A output current for  
3.3-V to 5-V conversion with up to 97% high  
efficiency. The device supports a programmable  
constant output current to control power delivery, so  
to save power path components and lower total  
system thermal dissipation effectively.

Up to 97% Efficiency Synchronous Boost  
Up to 3.5-A IOUT for 3.3-V to 5-V Conversion  
10-A 14-mΩ/14-mΩ Internal Power Switches  
Programmable Constant Output Current  
Output Current Monitor  
10-µA IQ under Light Load Condition  
Boost Status Indication  
True disconnection during shutdown  
Fixed 5.1-V Output Voltage (TPS61235P) or  
Adjustable Output Voltage from 2.9-V to-5.5 V  
(TPS61236P)  
The device only consumes a 10-µA quiescent current  
under a light load condition, and can report load  
status to the system, which make it very suitable for  
Always-On applications. With the TPS6123x, a simple  
and flexible system design can be achieved,  
eliminating external power path components, saving  
PCB space, and reducing BOM cost.

Thermal Protections  
2.5 mm x 2.5 mm VQFN Package  
2 Applications  
In shutdown, the output is completely disconnected  
from the input, and current consumption is reduced to  
less than 1 µA. Other features like soft start control,  
reverse current blocking, over voltage protection, and  
thermal shutdown protection are built-in for system  
safety.
